Polo Black - Polo Double Black...is there actually any difference...?

May be few years back I was at a fragrance store trying this & that and the salesman showed me Black & Double black...I do not exactly remember what it was but it smelled very woody and pleasent....Anyways I thought that it was Polo Black...so I ordered it from eBay and I was very excited till the time I actually received it...since then it is lying in my shelf unused....may be it is the 'iced mango; which turns me off...and now when I want to smell Polo double black again I could not find it any stores here...still wondering if it was double Black that day...
So my question is...Is Double Black any different than Black? I could see Mango in the top notes of this as well...!!

I won't say which is better or worse as they each have their own superior qualities, but Double Black is more oriental, spicy and possibly more interesting. DB is certainly the more popular on Basenotes. Its actually quite interesting considering the sillage/projection AND longevity are generally better for the original Black rather than the popular DB. I've used a few short squirts of the original and receive compliments from strangers, where as the DB tends to go less noticed. Just my $0.02...
